Answer:
*2Kl+Pb(NO3)2=PbI2+2KNO3: double replacement.
*2Al+3CuSO4=Al2(SO4)3+3Cu: single replacement.
*C2H5OH+3O2=2CO2+3H2O: combustion.
Explanation:
Hello there!
In this case, according to the required, it turns out necessary for us to recall the five types of reactions, combination, decomposition, single and double replacement and combustion as shown on the attached figure.
In such a way, since the first reaction follows the pattern AB+CD-->AD+CB we infer it is double replacement; the second reaction follows the patter A+BC-->AC+B and therefore it is single replacement; and the last one follows the pattern of combustion reaction due to the presence of CO2 and H2O on the products side.
Regards!
Answer:
Polar Zones - Coldest Temperature
Temperate Zones - Moderate Temperature
Tropical Zones - Hottest Temperature
Explanation:
The closer you are to the Equator, the hotter it gets, as the sun hits the middle of the Earth the most. At the poles, the sun hits it there the least, so it is the coldest. In between, we would have a mild between hot and cold.
*Remember that the Earth is at a tilt, and that is why we have seasons and why the Equator is so hot and the Poles are so cold.
The reaction between C2H6 and
Cl2 by addition is C2H4Cl2 or dichloroethane. It must be under the presence of
sunlight because halogen such as chlorine cannot easily react with the sigma
bond of alkane such as ethane.
Answer:
Filtration (The process of separating liquids and solids)
Explanation:
Filtration works best when the solute isn't dissolved in the solvent. Basically like how you can filter dirt or sand from water. The opposite of this would be if water and sugar where mixed together you cannot unmix this duo with filtration but with the example given you can use the process of filtration to rid the gasoline of sand.
